WINDOW-SASH CONSTRUCTION.

Application filed March 25, 1927. Serial No. 178,194.

iThe present invention relates to windowv sashefl of' a type which may be used in a construction where the sashes have plates which extend through openings in the jamb s face into enlarged chambers within the amb.

A Window of this type is fully described in vmy Patent No. 1,549,711 dated August 11th,

1925. lVhile the sashes made by this invention are primarily intended for use in such 1o a window, they may also be slightlyy modified for use in other types of window and still include my invention. According` to the present invention, the sashes are so built that the glass stops may be put in place without the use of screws. At the same time, the

method of manufacture is a highly economical one and will give a stiff sash even if light gauge metal is used.

In the accompanying drawings, I show two forms of my invent-ion. Fig. 1 is a section through a sash embodying one form of the invention primarily intended for use with fairly heavy metal; Figl 2 is a plan view of a lower corner of. the sash shown in Fig. 1; Fig. 3 is a section through a sash made of flexible metal such as light gauge steel or bronze; Fi 4 is a shadow view of a corner of a partia ly completed sash of the t pe shown in Fig. 3, and Fig. 5 isa rediiiced scale view showing of the manner in which the glass stops are inserted in eitherof the foregoing forms.

As shown in Fig. 1, the sash is made up of a plate 2 bent back on itself at 4 so as to leave a crack 6 between. the two fiat surfaces. An offset portion 8 is provided of the proper lengthto form a rabbet for the glass', and the plate is then bent on in the original direction at 10. As shown in Fig. 2 the corners of the sash are mitred and a triangular piece 12 is inserted in the crack 6 of each adjacent section of the sash. The piece 12 is -spot welded in place. In addition, the mitred joint may be spot or butt welded so as to strengthen the mitred corners. The glass stop has a main portion 14 of a thickness just suiiicient to 4squeeze into the crack 6, and is bent back on itself at 16, so as to strike against the offset portion 8 of the sash thus limiting the distance that the glass stop can be pushed into the crack 6.

As shown in Fig. 5 the two upper corners of the glass stops are mitred, whereas the side members come down straight andthe bottom member fits in between the tw'oside for light gauge metal of bronze.

stop to ride upward, these stops will all be locked into place without the use of screws. It may be noted that the main portion 14 of the glass stop doesnot extend all the way' to the bottom oi crack 6. Thus if any putty works into this crack, it will be pushed towards the bottom when the glass sto is put 1n place and will not interfere with t e glass stop. Also by having the members 2 and 4 connected a substantial distance from the position of the innermost edge of the glass stop, t-hese members can advantageously be arranged to maintain a pinch or spring pressure on the glass stop.

In the form shown'in Fig. 3 the Sash 2 has a portion 4 corresponding to portion 4 and forming a crack 6', and has an offset portion 8 and a portion 10 corresponding to the portion 10. YIn addition, it has a portion 11 bent back against the portion 10 and extending beyond the portion 8 leaving a crack 13 between the two. A member 15 is adapted to have one leg pushed intothe crack 13 and completes a box-like structure to give rigidity to the sash. The member 15 may beheld in place by a few spots of solder applied at spaced intervals. This form of construction is particularly. useful In assembling the form of sash shown in Fig. 3, members 15 are cut away a short distance'at the corner, thus leaving at each corner an opening extending into the box of the sash. A plug of putty as indicated at 17 is inserted in-each channel and then after the sash is warmed, hot solder is poured into the' channel and the corner squared out with the solder. A member 12 corresponding to the member 12 mayV also be used.

The glass stops 14' are similar-to the glass stops 14 and are inserted in the manner already described.

What I claim is:

1. A window sash construction in which eachside of the sash frame comprises a sheet metal member `bent to form a glass rabbet and bent to form plate, parallel with the glass, which plate comprises two thicknesses of the metal s aced apart n small distance, and in which t 1e glass sto .s comprise metal plates adapted to slip on y part way into the spaces between said two thicknesses of metal and to be held in place by spring pressure.

2. A construction as specified in claim 1, in which the sash frame members are united at the corners by the aid of metal plates in the spaces between said two thicknesses of metal.

3. A` window sash construction in which u box-like tube, and in which the glass stops comprise metal lmembers ada ted to slip into the spaces formed in said p ates.

4. A construction as specified in claim 3,

in which the sash frame members are united at the corners by. the aid of solder poured into such box-like tubes.
